Efficiency VS Input Voltage
EFFICIENCY (%)
The FDC40 series required a minimum 10% loading on the output to maintain
specified regulation. Operation under no-load condition will not damage these
devices, however they may not meet all listed specification.
Cross regulation:
Dual output—Asymmetrical load 25% to 100% full load
Triple output – 3.3V / 5V 100% load and one of auxiliary 100% load, other
auxiliary load change from 25% to 100% load
Simulated source impedance of 12uH. 12uH inductor in series with +Vin.
The ON-OFF control pin voltage is reference to negative input.

Application of synchronization
1. The unit is capable of external synchronization from an
independent time base with a switching rate between 200kHz
and 215kHz
2. The amplitude of the synchronizing pulse train is TTL
compatible
3. The duty cycle of the CLK should be 20% high and 80% low
4. Synchronization is referenced to negative input (-Vin)
